Knife Gate Valves

Product Description

The UTVC  knife gate is an uni-directional lug type valve designed according to MSS-SP-81 and TAPPI TIS 405-8 for industrial service applications. The design of the body and seat assures no clogging shut off on suspended solids in industries such as:

Pulp and Paper

Power plants

Mining

Chemical plants

Wastewater treatment plants

Sizes:                                                  DN 50/2 to DN 500/36 (larger diameters on request)

Working pressure:                           DN 50/2 to DN 400/20 DN 500/20

Standard flange connection:         DIN PN 10 and ANSI B16.5 (class 150)

BODY:

Lug type one piece integrally cast stainless steel body with reinforced ribs in larger diameters for extra body strength. Internal cast gate wedges and guides allows for tighter shutoff. Port design follows the MSS-SP-81 and Tape TIS 405-8 standards. The internal design of the valve avoids any buildup of solids that would prevent the valve from closing.

GATE:

Standard AISI 316 stainless steel gate. The gates are polished and lapped to attain a greater seal between the gate and both the packing and the seat. The bottom of the gate edge is also machined to a bevel, so that it cuts through the solids for a tighter seal in the closed position.

SEAT:

(resilient) Unique design that mechanically locks the seal in the internal of the valve body with a stainless steel retainer ring. Standard EPDM also available in different materials such as Viton, PTFE, etc. PACKING:

Long-life packing with several layers of PTFE impregnated fibre plus an EPDM o-ring, with an easy access packing gland ensuring a tight seal. Long-life braided packing is available in a wide range of materials. The standard stainless steel stem offers a long corrosion resistant life. For rising stem actuators only, a stem protector is provided for additional protection against dust while the valve in the open position.

STEM:

The standard stainless steel stem offers a long corrosion resistant life. For rising stem actuators only, a stem protector is provided for additional protection against dust while the valve in the open position

ACTUATORS:

Made of stainless steel (EPOXY coated carbon steel available on request). Compact design makes it extremely robust even under the most severe conditions. All actuators supplied by Usmani Valve are interchangeable, and supplied with an standard mounting kit for installation purposes on site. EPOXY COATING:

The epoxy coating on all ORBINOX cast iron and carbon steel valve bodies and components is electrostatically applied making the valves to be corrosion resistant with a high quality finished surface. The Usmani Valve standard color is RAL-5015 blue.
